Officially, April 11 will be the day that Microsoft begins sending out the Windows 10 Creators Update to PCs. But Microsoft said Thursday that advanced users can get Windows 10 Creators Update on April 5, about a week before April 11—and you don’t have to be on the Insider program, either.

What Microsoft appears to mean by "advanced user" is anyone willing to take the initiative to download the update via the Update Assistant, rather than wait to have the Windows 10 Creators Update pushed to your PC via Windows Update.

Microsoft also revealed the date when the Windows 10 Creators Update will begin pushing out to Windows phones: April 25. In this case, Microsoft will again send out the Windows 10 CU update in phases, presumably to newer phones like the HP Elite x3 first. Given the relatively tiny number of Windows phones, however, it’s likely that most will be upgraded relatively quickly.
